i had cachyOS installed for a couple of months but was plagued with random system freezes (only hard reset possible, no leads in journalctl). i tracked it down to an issue with the combination of wayland, KDE plasma and the kernel or at least that’s what i could gather from web searches. i had at least one of those freezes per week, often more.
i am now on kubuntu which basically has the same combination of things (wayland and KDE) that should cause the problem but it has been running fine for three weeks, no freezes. so something with the cachy kernel didn’t agree with my system.
i was now told i could use the arch kernel on cachyOS, which was news to me. i tried switching to the cachy LTS kernel but the issue persisted. i now wonder how does the compatibility of the linux kernel work? is it compatible because it is both arch linux? or would the kubuntu kernel also work on cachyOS?


Some quick googling tells me that their optimized packages require 12th gen or newer, so that is likely what was messing you up. here is the link I found if you are interested, but I think your hardware is just to old.
here it lists cpu’s dating back to “Intel 4th Gen Core (Haswell)”:

I can’t help you there, I don’t personally use cachy I am just making assumptions based upon what I have heard and how it works on other distros
thanks! nobody on the cachy forums brought this up. what would this mean for a different kernel? would switching to the arch kernel fix/circumvent this?
Packages != kernel, so probably not. I don’t know how power usery you want to be, if fine with some tinkering then staying with arch makes sense and as I said in the prior post I recommend endeavoros. If you want no tinkering, kubuntu is fine I would just lookup snaps and see what you are getting yourself into, and if that turns you away I would recommend mint lmde.
i tried endeavor os at some point but didn’t like it (don’t remember specifics). and i am not keen on kubuntu…
